Long time Vray user here, first time using Corona, although I've been quite curious about it for a while now. So I've finally made the jump and downloaded the demo, and converted a project into Corona mid production, which was a breeze thanks to the converter. In the end I was able to turn the project around better and even faster than it would have taken me to wrestle with vray to get the look I'm after or spend countless hours in post after every inevitable client change. And on a personal note, it's just a joy to work with. So I want to thank the dev team for such a top notch product. I'm already working towards completely switching over in the next month or so.
That being said, I did have some trouble with some elements that I just couldn't get on my own,
1.The full resolution image was rendered at 5k, 290 passes, and yet the image is still very noisy, especially the geometry at the back is very fuzzy. I should point out that I've used Rebus Farm to render the image. Since it was my first time with Corona I didn't know how to gauge how many passes I needed, so I've set it to 25RP which I thought is plenty for an exterior image like this, but Rebus does not support denoising so I couldn't utilize it. So my question is how many passes is enough for a scene like this? And is that indeed the solution or is there something else I'm missing?
2. This is not the typical case but since the pool here has glass walls, you can see in the image the pool is "wavy" on all sides, I've tried separating the top water surface from the rest, by both detaching it into a separate object, element, or mat id and then using the an identical material except with bump map disabled and that seems to have broken the absorption. Is there a way around this?
3. Caustics, I've tried searching on the forums and in the helpdesk and couldn't find a reliable way to get caustics, is there a way around this even if it needs to be rendered separately and comped in post?
Thank you
